Preferably, the handle 2 is fixedly connected with the rubber 6 at the top end inside, when a user fixes the whole chuck 1, the whole chuck 1 is fixed with the handle 2 through the rubber 6, and the rubber 6 has certain elasticity, so when the whole chuck 1 is put into use, the whole chuck 1 can effectively counteract the vibration force through the rubber 6 when put into use, and thus the drill bit can be free from the influence of vibration during working.
Preferably, the bottom fixedly connected with antiskid texture 5 of handle 2, the line of this texture is irregular to make the frictional force with user's palm increase, so before the user uses the drill bit to carry out work, during the clamping drill bit, can open mouth 7 through handle 2, at this moment, when user's hand is smooth or under the careless condition of use, can play skid-proof effect, has reduced and has opened the situation that the mouth 7 is opened and is acutely foldd up and cause the injury to the user.
Preferably, the main body spring 11 is fixedly connected to the middle of the bottom of the chuck body 1, so that when a user clamps a drill before using the drill to work, the main body spring 11 can generate upward thrust on the handle 2, and through the conical design of the chuck body 1, the thrust can be converted into pressure of the chuck body 1 on the drill, and the drill can be stably fixed at the chuck, so that unstable situations are reduced.
Preferably, the support rod 14, the bearing 15 at the top of the support rod 14, the movable chuck 13 on the left side of the bearing 15 and the fixture block 12 in the middle inside the handle 2 form an opening mechanism together, so that before a user uses the drill bit to work, when the drill bit is clamped, the support rod 14 can generate upward jacking force on the middle part of the movable chuck 13, the jacking force on the middle part can enable the movable chuck 13 to be opened outwards, only the handle 2 is rolled downwards, the fixture block 12 in the handle 2 also generates downward force on the movable chuck 13, and the support rod 14 generates upward jacking force on the movable chuck 13, so that the chuck 1 can be opened integrally, then the drill bit is placed into the chuck 1, the handle 2 is loosened, and the drill bit can be firmly grasped, so that the setting can be more convenient for the user to clamp the drill bit.
Preferably, the latch bolt 16 is a drill bit fixing mechanism which is composed of the latch bolt 16, a latch bolt hole diameter 17 on the right side of the latch bolt 16 and a part spring 18 inside the latch bolt hole diameter, so that a user can clamp a drill bit more easily through the internal latch bolt 16 before using the drill bit to work, and the drill bit is fixed more easily, because the top of the drill bit is provided with two small holes, when the drill bit is placed into the drill bit hole diameter 8, the latch bolt firstly retracts into the latch bolt hole diameter 17 due to the extrusion of the drill bit in the drill bit hole diameter 8, and after the drill bit is completely inserted, the latch bolt enters the small hole at the bottom of the drill bit due to the elasticity of the spring, so that the drill bit is fixed, and the purpose of fastening the drill bit is achieved.
The working principle is as follows: firstly, the rubber 6 is fixedly connected to the top end inside the handle 2, so that a user can firmly grasp the chuck 1 through the rubber 6 when clamping the drill bit before using the drill bit to work, and at the moment, the chuck 1 transmits the force to the force for grasping the drill bit, so that the chuck 1 can firmly grasp the drill bit, and the drill bit can be prevented from being influenced by vibration during working.
Then, the bottom of the handle 2 is fixedly connected with the anti-skidding texture 5, so before a user uses the drill bit to work, the opening 7 can be opened through the handle 2 when the drill bit is clamped, at the moment, the anti-skidding effect can be achieved under the condition that the user slips or carelessly opens the opening 7, and the condition that the user is injured due to severe folding when the opening 7 is opened is reduced.
Then, the main body spring 11 is fixedly connected to the middle of the bottom of the whole chuck 1, so that when a user clamps the drill before using the drill to work, the spring can generate internal pressure on the chuck 1, the pressure is converted into the pressure of the chuck 1 on the drill through the chuck 1, and the drill can be stably fixed at the chuck, so that the unstable situation is reduced.
Next, the supporting rod 14 and the bearing 15 at the top of the supporting rod 14, the movable chuck 13 at the left side of the bearing 15 and the clamping block 12 in the middle of the inside of the handle 2 jointly form an opening mechanism, so that a user can generate outward opening force on the movable chuck 13 through the supporting rod 14 before using a drill bit to work, and when clamping the drill bit, the rubber 6 at the top end of the handle 2 can generate inward pressure on the chuck 1, only the handle 2 is rolled down, the clamping block 12 inside the handle 2 also generates downward force on the movable chuck 13, the supporting rod 14 generates upward jacking force on the movable chuck 13, the chuck 1 can be opened only by the user, the drill bit is put into the chuck, and the clamping bit is firmly grasped, so that the clamping bit can be more conveniently clamped by the user.
Finally, the latch 16 is a drill bit fixing mechanism composed of the latch 16, a latch aperture 17 on the right side of the latch 16 and a part spring 18 inside the latch aperture, so that a user can clamp the drill bit more easily through the internal latch 16 before using the drill bit to work, and the drill bit is fixed more easily, and the latch 16 can retract into the latch aperture 17 when clamping the drill bit, so that the drill bit can enter more easily, and after the drill bit is clamped, the latch 16 springs the latch 16 into the drill bit aperture through the part spring 18 in the latch aperture 17, and enters the fastener of the drill bit, so that the clamping is convenient, and the drill bit can be fixed.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
