Preferably, the lateral wall fixing sleeve of the adjutage is connected to Anti-slip cover.
Compared with prior art, the utility model has the beneficial effects that：This extendible Multifunctional spanner structure is simple, leads to
Cross addition mobile clamp arm, mobile bar, graphite block, roller bearing, rotating bar, fixed plate, adjutage, spur rack, ring gear, swingle
With the structures such as Anti-slip cover, when fixing clamp arm and mobile clamp arm are after the size according to bolt mixes up distance, in order to enable spanner
It can reach in gap and work, turn swingle, the rotation of swingle will drive ring gear rotation, so that spur rack
It moves upwards, so that fixed plate is moved to outside adjutage, achievees the effect that brace arm extends, the presence of Anti-slip cover can be with
Anti-skidding effect is played, during mobile clamp arm movement, movement of the mobile bar in the second groove can all contact graphite
Block, so as to have the function that lubrication, therefore the device can achieve the effect that multipotency.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is A structure enlargement diagram.
In figure：Fixing clamp arm 1, mobile clamp arm 2, mobile bar 3, graphite block 4, roller bearing 5, rotating bar 6, fixed plate 7, adjutage
8, spur rack 9, ring gear 10, swingle 11, Anti-slip cover 12.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2,：
A kind of extendible multifunctional wrench, including fixing clamp arm 1 offer the first groove in fixing clamp arm 1, and first is recessed
The side wall of slot is rotatably connected to the both ends of rotating bar 6, and fixing sleeve is connected to roller bearing 5 in rotating bar 6, and the threaded upper ends of roller bearing 5 connect
It is connected to mobile bar 3, and one end of mobile bar 3 is run through the side wall of the first groove and extended to outside the first groove, the upper end of mobile bar 3
It is fixedly connected with mobile clamp arm 2, and mobile clamp arm 2 is contradicted with the side close to each other of fixing clamp arm 1 and connected, mobile clamp arm 2 is leaned on
