Abstract
The automobile spark plug is replaced with the broken end taking-out device. A straight knife with proper size is clamped on the broken end, then the end is broken into the cylinder by force, and then the broken spark plug is sucked out by using a magnetic rod. This method is prone to damage to the threads on the cylinder and can also lead to damage to the engine if not sucked clean. The composition of the utility model comprises: spanner (1) and tapping head (2), the tapping head include straight-bar (24), the one end of straight-bar have toper spinneret (23), the other end has square head (24), the straight-bar on cover have sliding sleeve (22) and with sliding sleeve sliding fit. The utility model is used for replacing and taking out the broken ends of the automobile spark plugs.
Description
Technical Field
The utility model relates to a broken end replacing and taking-out device for an automobile spark plug.
Background
When the spark plug is installed and removed, if an operator uses excessive moment, usually 35 N.m-40 N.m or more, the metal shell of the spark plug is likely to be broken, usually the metal threaded part of the spark plug is left on the cylinder body, and this is usually achieved by clamping a straight cutter with proper size on the broken end, then removing the end head to be smashed into the cylinder, and then removing the smashed spark plug by using a magnetic rod. This method is prone to damage to the threads on the cylinder and can also lead to damage to the engine if not sucked clean.
Disclosure of Invention
The utility model aims to provide a device for replacing broken ends of an automobile spark plug, which aims to solve the problems in the prior art.
The above object is achieved by the following scheme:
the utility model provides a broken end remove device is changed to car spark plug, its constitution includes spanner and tapping head, the tapping head include the straight-bar, the one end of straight-bar have the toper wire head, the other end has square head, the straight-bar on the cover have the sliding sleeve and with sliding sleeve sliding fit.
The automobile spark plug replacement broken end taking-out device comprises a handle, a spanner and a sleeve, wherein the sleeve is fixed at the end part of the spanner, and the sleeve is provided with a square groove.
The automobile spark plug replacement broken end taking-out device is characterized in that a sliding groove is formed in the straight rod, and a sliding block matched with the sliding groove is arranged on the inner wall of the sliding sleeve.
Advantageous effects
1. The broken head is taken out by tapping the tapping head into the broken head, so that the screw thread on the air cylinder can be prevented from being damaged.
2. The utility model is provided with the sliding sleeve, and the sliding sleeve slides downwards under the action of self gravity to be contacted with the broken end of the spark plug in the tapping process, so that the wire head is blocked in the tapping process, and filaments are prevented from falling into the cylinder in the tapping process.
