Abstract
The invention discloses a lithium battery brushless spanner, which comprises a handle, wherein a button and a bolt are arranged on the handle, one end of the button stretches into the handle, a chute is arranged on the button, a circular hole is formed in the end part of the chute, the diameter of the circular hole is larger than the width of the chute, the bolt is divided into three sections, two ends of the bolt are blocking parts, the middle of the bolt is a passing part, the diameter of the passing part is smaller than the width of the chute, the diameter of the blocking part is larger than the width of the chute and smaller than the diameter of the circular hole, when the lithium battery brushless spanner is used, the passing part is positioned in the chute, the button can be pressed, when a product is placed on the ground, the end part of the blocking part contacts with the ground, the blocking part is blocked into the circular hole, and at the moment, the button can not be pressed. Therefore, when the lithium battery brushless spanner is placed on the ground in a short time, the child cannot press the starting button when the lithium battery brushless spanner is placed on the ground, and dangers are avoided.
Description
Technical Field
The invention relates to a lithium battery brushless wrench, in particular to a lithium battery brushless wrench with high safety.
Background
After a bolt is screwed, a plurality of people can not disconnect the power supply when the lithium battery brushless spanner is in a neutral gear of the bolt, the lithium battery brushless spanner is often placed on the ground, and if a child is curious at this time, the lithium battery brushless spanner can be started by touching the switch accidentally, so that danger is caused.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a lithium battery brushless wrench which cannot be started when the wrench is placed on the ground in an inverted mode, so that safety is ensured.
The technical scheme adopted for solving the technical problems is as follows: the utility model provides a lithium electricity brushless spanner, includes the handle, be provided with button and bolt on the handle, button one end stretches into in the handle, be provided with a spout on the button, the tip of spout is provided with circular hole, circular hole's diameter is greater than the width of spout, the bolt divide into the syllogic, the both ends of bolt are blocking portion, the centre of bolt is through the portion, the diameter of through the portion is less than the width of spout, blocking portion's diameter is greater than the width of spout is less than circular hole's diameter, during the use, through the portion is located in the spout, the button can be pushed, when the product is put subaerial, blocking portion's tip contacts with ground, blocking portion card is gone into in the circular hole, the button can't be pushed this moment. Therefore, when the lithium battery brushless spanner is placed on the ground in a short time, the child cannot press the starting button when the lithium battery brushless spanner is placed on the ground, and dangers are avoided.
In the above technical scheme, preferably, a spring is sleeved on the blocking portion, a baffle is fixed at one end of the blocking portion, and two ends of the spring are respectively in contact with the baffle and the handle.
In the above technical solution, preferably, a battery pack is disposed at the bottom of the handle.
In the above technical solution, preferably, an anti-slip strip is disposed on the outer side of the handle.
The beneficial effects of the invention are as follows: when the product is placed on the ground, the end part of the blocking part is contacted with the ground, and the blocking part is clamped into the circular hole, so that the button can not be pressed. Therefore, when the lithium battery brushless spanner is placed on the ground in a short time, the child cannot press the starting button when the lithium battery brushless spanner is placed on the ground, and dangers are avoided.
Drawings
The invention will be further described with reference to the drawings and examples.
Fig. 1 is a schematic diagram of the present invention.
Fig. 2 is a cross-sectional view taken along A-A of fig. 1.
Fig. 3 is a schematic view of the button and latch cooperation.
Description of the embodiments
Referring to fig. 1 to 3, the lithium battery brushless wrench comprises a handle 1, wherein a button 2 and a bolt 3 are arranged on the handle 1, one end of the button 2 extends into the handle 1, a chute 21 is arranged on the button 2, a circular hole 22 is formed in the end part of the chute 21, and the diameter of the circular hole 22 is larger than the width of the chute 21.
The bolt 3 divide into three sections, the both ends of bolt 3 are blocking portion 31, the centre of bolt 3 is through portion 32, the diameter of through portion 32 is less than the width of spout 21, blocking portion 31 is greater than the diameter of spout 21 is less than the diameter of circular hole 22, the cover is equipped with spring 4 on blocking portion 31, one end is fixed with baffle 5 on the blocking portion 31, the both ends of spring 4 respectively with baffle 5 with handle 1 contacts.
The bottom of the handle 1 is provided with a battery pack 6. An anti-slip strip 11 is arranged on the outer side of the handle 1.
When the product is placed on the ground, the end part of the blocking part is contacted with the ground, and the blocking part is clamped into the circular hole, so that the button can not be pressed. Therefore, when the lithium battery brushless spanner is placed on the ground in a short time, the child cannot press the starting button when the lithium battery brushless spanner is placed on the ground, and dangers are avoided.
