A kind of rotary screw device, comprise described in holding up nail block and being fixed on and hold up the handle followed closely on block, it is characterized in that, described holding up on nail block has the through hole passed for nail, the hole wall of described through hole have at least two grooves be oppositely arranged, described groove internal fixtion has spring, and the outer end of described spring is fixed with the clamp structure for clamping nail.
Preferably, described clamp structure comprises the gripper frame be fixed on spring, is provided with the roller bearing that can rotate in described gripper frame.
Preferably, described roller bearing has the arc cylinder of indent.
Preferably, described clamp structure is a grip block, and the first end face of described grip block is fixed on described spring, and the opposing end surface of the first end face of described grip block is the clamping face of indent arc.
Preferably, described clamping face has graphite linings.
Preferably, described in hold up nail block bottom surface on there is the strip T-slot parallel with described handle, described T-slot is provided with gripper shoe.
A kind of rotary screw device provided by the utility model, clamps nail under the action of the spring by the clamp structure be oppositely arranged, and spring can realize flexible according to the size of the nail inserted automatically, and such rotary screw device just electrodelessly can be suitable for the nail of all size.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model rotary screw device.
Fig. 2 is the structural representation of gripper shoe in the utility model.
Detailed description of the invention
Below just accompanying drawing in conjunction with the embodiments, is described in further detail detailed description of the invention of the present utility model, is easier to understand, grasp to make technical solutions of the utility model.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Present embodiments provide a kind of rotary screw device, as shown in Figure 1 and Figure 2, comprise and hold up nail block 100, handle 200 and gripper shoe 300.Handle 200 is fixed on to be held up on nail block 100.Hold up on nail block 100 and have the through hole 110 passed for nail, the hole wall of through hole 110 has at least two grooves be oppositely arranged 120, the present embodiment adopts two pairs of grooves 120, that is, hole wall has four grooves 120.Be provided with spring 130 in groove 120, the inner of spring 130 is fixed in groove 120, and the outer end of spring 130 and the blessing structure for accommodating nail are connected.
Accommodate structure and comprise following two kinds of embodiments:
The first embodiment of clamp structure, specifically, consults Fig. 1, and accommodate structure and comprise the gripper frame 140 be fixed on spring 130, be provided with the roller bearing 150 that can rotate in gripper frame 140, roller bearing 150 has the arc cylinder of indent.Preferably, the roller bearing 150 of two longitudinal arrangements is set, so that stable blessing nail in a gripper frame 140.
Accommodate the second embodiment of structure, do not illustrate in the drawings, specifically, blessing structure is grip block, first end face of grip block is fixed on the outer end of spring, and the opposing end surface of the first end face of grip block is the clamping face of indent arc, and clamping face is used for and nail leans.Clamping face has graphite linings to reduce the friction between nail and clamping face.
During use, nail is inserted through hole 110, the diameter of nail is greater than the gap accommodating structure and surround, and inserting spring 130 in the process of nail can suitably be compressed, and the spring 130 of compression reacts on blessing structure, makes clamp structure clamp nail.
Further, hold up on the bottom surface of nail block 100 and there is the strip T-slot 160 parallel with handle 200, T-slot 160 is provided with gripper shoe 300.The bottom surface holding up nail block 100 is plane, so just cannot stablize and be fitted in Machining of Curved Surface face, and just can install gripper shoe 300 on the bottom surface holding up nail block 100 for Machining of Curved Surface face, the shape of gripper shoe 300 can make according to the shape of machined surface.Consult Fig. 2, gripper shoe 300 shown in Fig. 2 can be fitted on tubulose machined surface preferably.Gripper shoe 300 has T-shaped bar and T-slot 160 is connected.
Should be understood that; the foregoing is only preferred embodiment of the present utility model; be not sufficient to limit the technical solution of the utility model; for those of ordinary skills; within spirit of the present utility model and principle; can be increased and decreased according to the above description, replaced, converted or improved, and all these increases and decreases, replacement, conversion or the technical scheme after improving, all should belong to the protection domain of the utility model claims.
