Embodiment 1

[0038] This embodiment provides a multi-head linkage wrench, such as Figure 1 to Figure 2 As shown, the multi-head linkage wrench includes a wrench head 100, a driving gear 110 and a driven gear set, wherein the driving gear 110 is rotatably connected to the wrench head 100, and the driven gear set includes a plurality of driven gears 120 that are sequentially connected. 120 is rotatably connected to the wrench head 100 , and one of the driven gears 120 is engaged with the driving gear 110 , and the driven gear 120 is provided with a sleeve 130 for clamping the nut. In this embodiment, when the driving gear 110 is controlled to rotate, the driving gear 110 can drive the driven gear 120 meshed with it to rotate synchronously, and at the same time, the multiple driven gears 120 meshed in turn will also rotate synchronously, thereby driving the sleeve 130 Synchronous rotation, when used for loading and unloading multiple bolts at the same time, according to the position and spac...

Embodiment 2

[0049] The multi-head linkage wrench provided in this embodiment is different from the multi-head linkage wrench provided in Embodiment 1 in that: the handle 200 includes a first handle 210 and a second handle 220, and the second handle 220 is arranged on the first handle 210 The end of the first handle 210 is connected to the driving gear 110 , the end of the second handle 220 is hinged with a rocker arm 230 , and a handle 160 is provided on the wrench head 100 .

[0050] Optionally, the first handle 210 is provided with an external thread, the first installation hole 113 opened on the driving gear 110 is provided with an internal thread matching the external thread, and the first handle 210 is screwed to the driving gear 110 .

[0051] In this embodiment, when controlling the rotation of the driving gear 110, the relevant operator holds the grip part 160 with one hand, so that it can be taken more stably and reliably, and the other hand rotates the rocker arm 230, thereby dri...

Abstract

The invention belongs to the technical field of wrenches, and discloses a multi-head linkage wrench. The multi-head linkage wrench comprises a wrench head, a driving gear and a driven gear set. The driving gear is rotationally connected to the wrench head; the driven gear set comprises a plurality of driven gears which are sequentially connected in a transmission mode, the driven gears are rotationally connected to the wrench head, one driven gear is connected with the driving gear in a meshed mode, and a sleeve used for being connected with a nut in a clamping mode is arranged on each driven gear. When the driving gear rotates, the driven gear meshed with the driving gear is driven to rotate synchronously, meanwhile, the driven gears meshed in sequence can also rotate synchronously, and therefore the sleeves are driven to rotate synchronously, and when a plurality of bolts are assembled and disassembled at the same time, the corresponding sleeves can be selected to clamp the nuts of the bolts to be screwed according to the positions and the intervals of different bolts. Therefore, the plurality of bolts with different intervals can be screwed, assembled and disassembled at the same time, the structure is simple, the use compatibility is high, the working efficiency of operators is effectively improved, and the overall efficiency of electric power operation is also improved.

Description

technical field [0001] The invention relates to the technical field of wrenches, in particular to a multi-head linkage wrench. Background technique [0002] During the disassembly and maintenance process of electrical equipment, operators will regularly overhaul and replace relevant components in the electrical device. When loading and unloading relevant components, the relevant personnel usually use a wrench to screw the bolts in the device accessories. The wrench in the prior art can only screw one bolt at a time, and the compatibility is poor, and it is impossible to screw and load multiple bolts at different positions and different distances at the same time, which makes the work efficiency of the operator low during the operation , Invisibly increase the workload of the operator and affect the overall maintenance efficiency of the whole power operation. Contents of the invention [0003] The purpose of the present invention is to provide a multi-head linkage wrench t...
