Abstract
The utility model belongs to the technical field of manual tools, in particular to a ratchet wrench, which comprises a rod body (1), wherein the center of the rod body (1) is provided with a one-way ratchet structure, and both ends of the rod body (1) are provided with positioning holes (2); the device is provided with a special braking structure, and the connecting rod can prop and hold the ratchet wheel by inserting an object which can prop and hold a triangular structure of the connecting rod into the through hole (1-1), so that the braking of the ratchet wheel is realized, the structure of braking by a manual shifting block of the traditional ratchet wrench is omitted, and the ratchet wrench can be suitable for complex working conditions.
Description
Technical Field
The utility model belongs to the technical field of hand tool, especially, relate to a ratchet spanner.
Background
Traditional ratchet spanner sets up the tip with the spanner with ratchet structure, through external shifting block in order to realize switching-over or braking, but to complicated operating mode, under the condition that the shifting block was not convenient for stir to the staff, can't realize ratchet spanner's braking effect, consequently need design a neotype ratchet spanner.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an effectual problem among the above-mentioned background of solution has proposed a ratchet spanner, and concrete technical scheme is as follows:
a ratchet wrench comprises a rod body (1), wherein a one-way ratchet structure is arranged in the center of the rod body (1), and positioning holes (2) are formed in two ends of the rod body (1);
the one-way ratchet structure comprises: the ratchet wheel (3) is rotatably arranged in the rod body (1), the shifting block (4) is used for limiting the unidirectional rotation of the ratchet wheel (3), and the braking structure is used for braking the ratchet wheel (3); a hexagonal through hole (3-1) matched with an external screw is formed in the center of the ratchet wheel (3);
the brake structure comprises a connecting rod (5) arranged in a rod body (1) in a sliding mode, one end of the connecting rod (5) is a clamping hook structure (5-1) capable of being matched with the ratchet wheel, the other end of the connecting rod is a triangular structure (5-2), the connecting rod (5) is matched with a spring (6) clamped in the rod body (1), and the triangular structure (5-2) of the connecting rod (5) is arranged at a through hole (1-1) in the rod body (1) so that the connecting rod (5) can brake the ratchet wheel (3) by supporting the triangular structure in the through hole (1-1) through the outside.
Preferably, the shifting block (4) is hinged on the rod body (1), and a second spring (7) is arranged between the shifting block (4) and the rod body (1);
compared with the prior art, the beneficial effects of the utility model reside in that: 1. the ratchet structure is arranged in the center of the wrench, so that the assisting rod can be inserted into the positioning holes at the two ends of the wrench to realize assisting when the device is used; 2. the device is provided with a special braking structure, and an object which can support a triangular structure of the connecting rod is inserted into the through hole 1-1, so that the connecting rod can support the ratchet wheel, and the braking of the ratchet wheel is realized, thereby saving a structure for braking a manual shifting block of a traditional ratchet wrench, and enabling the ratchet wrench to be suitable for complex working conditions.
