The control rod assembly 107 can drive the rotating sleeve 108 to move together, so that the rotating sleeve 108 can be in sliding contact with the inclined position on the side of the front axle accessory of the bridge housing, and at the same time, one end of the front axle accessory of the bridge housing is pushed to tilt up, which is convenient for removing the front axle accessory of the bridge housing and improves the disassembly efficiency; a bottom part structure 2; two bottom part structures 2 are embedded and installed at the bottom of the composite welding tooling 1, a spring is installed at the middle position of the top end of the bottom part structure 2, and the top end of the spring is in contact with the bottom of a contact block structure 206. Four symmetrically arranged support plates 204 are fixed at the top end of the bottom part structure 2. The inclined support plates 204 are made of elastic metal, and the top ends of the support plates 204 are in contact with the bottom of the contact block structure 206, so that the spring and the support plates 204 are stressed together to support the contact block structure 206. After the front axle accessory of the bridge housing is placed, the impact force generated by the fall of the front axle accessory of the bridge housing can be eliminated, the impact force can be effectively eliminated, and large collisions can be avoided.

[0026] In the embodiment of the present disclosure, as Figure 3 With Figure 4 shown, two rectangular bottom grooves 101 are arranged at the bottom of the composite welding tooling 1, so that the contact block structure 206 can be inserted into the inside thereof for guiding displacement. Four side grooves 102 are respectively arranged on both sides of the composite welding tooling 1, so that the plug-in member 202 can be inserted into the inside thereof and connected with the connecting head 201 to limit and fix the bottom part structure 2; the mounting component 103 is fixed at the side of the top end of the composite welding tooling 1 through bolts, and a T-shaped guiding groove 104 is formed inside the mounting component 103, so that the moving block assembly 106 can be used for guiding displacement inside the mounting component 103; a guiding rod 105 in a round rod shape is fixed inside the guiding groove 104, and a spring is sleeved outside the guiding rod 105 to generate a boosting effect by pushing the moving block assembly 106, so that the moving block assembly 106 can be conveniently controlled to displace.

[0027] In the embodiment of the present disclosure, as Figure 5 With Figure 6As shown, two connectors 201 are welded to both ends of the bottom part structure 2 respectively for connecting with the plug-in part 202. A U-shaped plug-in part 202 is inserted into the inner parts of the two connectors 201 on the same side. The plug-in part 202 penetrates through the side slots 102 at the same time, connecting and fixing the connector 201 and the bottom part structure 2 together. An adsorption structure 203 is fixed at the middle position of the plug-in part 202.
