Abstract
The invention relates to a perforating bur. The perforating bur comprises a rig and is characterized in that a rotating head is arranged in the front of the rig, a universal joint is connected to the front end of the rotating head, the front part of the universal joint is connected with a drill connector, and a direction locating sleeve sleeves the universal joint and can move forwards and backwards. When the direction locating sleeve moves forwards, the direction of the universal joint is set to be forward, and when the direction locating sleeve moves backwards, the universal joint restores the normal function. When a user wants to perforate a wall, the direction locating sleeve is enabled to move forwards, so that the rig and the drill can be in a linearly connected state to facilitate locating during perforation; after finish of location, the direction locating sleeve is enabled to move backwards, so that the rig and the drill can be in a universally connected state to facilitate perforation, and the phenomenon that the drill is stuck due to inaccurate angle of the rig is avoided.
Description
Technical field
The present invention relates to a kind of brightwork field, especially relate to a kind of grooved bit.
Background technology
Grooved bit is used to a kind of machine punched on wall, because wall is thicker, the drill adopted must be very long, and rig and drill bit are again rigid connections, so be easy to cause rotary head stuck, once drill bit is stuck when punching, will reverse with hand-held rig, the strain in the arm of people, be very dangerous, the present invention well solves existingly exists technical problem.
Summary of the invention
The invention provides a kind of grooved bit, it mainly solves existing grooved bit and is easy to cause rotary head stuck when punching, once drill bit is stuck, will reverse with hand-held rig, the strain in the arm of people, is very dangerous shortcoming.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals.
The invention discloses a kind of grooved bit, comprise a rig, it is characterized in that described rig front portion is provided with a swivel head, described swivel head front end is connected with a universal joint, and described universal joint front portion connects a bit connectors, the outer cover of described universal joint is equipped with a direction positioning sleeve, described direction positioning sleeve can move forward and backward, and when moving forward, universal joint direction is fixing forward, when positioning sleeve moves backward, universal joint recovers normal function.
As preferably: be provided with worm and gear between described swivel head and universal joint, conveniently turn to operation.
The invention provides a kind of grooved bit, when people will punch on the wall, just positioning sleeve is moved forward, rig and drill bit are in line connection status, and location during convenient punching, when location completes, just positioning sleeve can be moved backward, rig and drill bit is made to be universal connection status, convenient punching, the effect that drill bit will be caused stuck because the angle of rig is forbidden.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present invention.
Mark in figure: 1-rig: 2-swivel head: 3-universal joint: 4-bit connectors: 5-direction positioning sleeve: 6-worm and gear.
Detailed description of the invention
Understand for the ease of those of ordinary skill in the art and implement the present invention, and by reference to the accompanying drawings technical scheme of the present invention being described in further detail.
Embodiment: as shown in Figure 1, a kind of grooved bit of this example, comprise a rig (1), it is characterized in that described rig (1) front portion is provided with a swivel head (2), described swivel head (2) front end is connected with a universal joint (3), worm and gear (6) is provided with between described swivel head (2) and universal joint (3), described universal joint (3) front portion connects a bit connectors (4), described universal joint (3) outer cover is equipped with a direction positioning sleeve (5), described direction positioning sleeve (5) can move forward and backward, when moving forward, universal joint (3) direction is fixing forward, when its direction positioning sleeve (5) moves backward, universal joint recovers normal function.When people will punch on the wall, just positioning sleeve is moved forward, rig and drill bit are in line connection status, location during convenient punching, when location completes, just positioning sleeve can be moved backward, make rig and drill bit be universal connection status, convenient punching, the effect that drill bit will be caused stuck because the angle of rig is forbidden.
The foregoing is only specific embodiments of the invention, but architectural feature of the present invention is not limited thereto, any those skilled in the art is in the field of the invention, and the change done or modification are all encompassed among the scope of the claims of the present invention.
Claims (2)
1. a grooved bit, comprise a rig, it is characterized in that described rig front portion is provided with a swivel head, described swivel head front end is connected with a universal joint, and described universal joint front portion connects a bit connectors, the outer cover of described universal joint is equipped with a direction positioning sleeve, described direction positioning sleeve can move forward and backward, and when moving forward, universal joint direction is fixing forward, when positioning sleeve moves backward, universal joint recovers normal function.
2. a kind of grooved bit according to claim 1, is characterized in that being provided with worm and gear between described swivel head and universal joint, conveniently turns to operation.
