The invention relates to a static load deformation testing device for a holding pole. The static load deformation testing device comprises a lifting clamp holding pole, a test base for supporting the holding pole, a force applying mechanism for applying a static load to the holding pole and a test assembly for detecting the deformation degree of the holding pole. The test assembly includes a collection terminal and a plurality of wireless cord sensors; and the wireless cord sensors are disposed on the holding pole and are connected with the collection terminal via a wireless network. The static load deformation testing device has advantages: the wireless cord sensors are used for testing, so that the wiring amount of the test site is reduced; the multiple wireless cord sensors are used for multi-point detection of the holding pole to obtain an overall deformation curve of the holding pole, so that the test result becomes comprehensively; and with the test base, manual pole lifting is avoided, so that the safety of the test is improved.
