Technical Field
[0001] The utility model relates to the technical field of bottle openers, in particular to a bottle opener for the inner cover of a chemical reagent bottle. Background Art
[0002] A corkscrew is a common bottle opening tool, including ordinary plastic bottle openers, European bottle openers, T-shaped bottle openers, etc. The most common bottle opener is a wine cork bottle opener, but bottle openers are also used in other fields. For example, in a chemical laboratory, researchers need to use a bottle opener to open the caps of chemical reagent bottles, but the bottle openers on the market can only open the outer caps of chemical reagent bottles, and the inner caps of the reagent bottles need to be opened manually by researchers or pried open with tools such as tweezers. However, these two methods can easily cause contamination of chemical reagents during the opening process, and when the bottle contains corrosive liquids, it is easy to cause harm to the operator. Therefore, we have launched a bottle opener for the inner caps of chemical reagent bottles.
[0003] The existing technology has the following problems: the existing inner cap of the chemical reagent bottle fits tightly to the inner wall of the bottle mouth, making it difficult to remove it from the reagent bottle mouth; the existing inner cap of the chemical reagent bottle is mainly opened manually or pried open with tweezers when in use. Although the inner cap can be opened, both manual opening and tweezers prying are easy to contaminate the chemical reagent inside. Due to the lever principle used when prying with tweezers, it is easy for the tweezers to puncture the inner cap and contaminate the reagent in the bottle. Utility Model Content
[0004] The purpose of the utility model is to provide a bottle opener for the inner cover of a chemical reagent bottle to solve the problems raised in the above background technology.

[0009] Further preferably, the outer sides of the first inner support arm and the second inner support arm are both covered with a silicone layer, and the area covered by the silicone layer is an acid-proof area.
[0010] Further preferably, a rotating shaft is rotatably connected between the inner walls of the mounting groove, and the rotating shaft passes through the middle of the bottom end of the elastic arm. Two torsion springs are sleeved on the outer sides of both ends of the rotating shaft, and the two torsion springs do not contact the rotating shaft.
[0011] Further preferably, the two ends of the two torsion springs are respectively connected to the inner wall of the mounting groove and the outer side of the elastic arm, and an elastic reset structure is formed between the elastic arm and the handle through the two torsion springs.
[0012] Further preferably, a notch is provided in the middle of the second inner support arm, a guide groove is provided on the bottom surface of the power arm, and the top end of the elastic arm is in contact with the inner top surface of the guide groove.

[0022] In this embodiment, Figure 1 and Figure 2As shown, a first inner support arm 101 is provided at the bottom of the left end of the handle 1, and the first inner support arm 101 and the handle 1 are an integrated structure, the bottom end of the first inner support arm 101 is fixedly connected to the first inner support block 102, the bottom end of the power arm 2 is provided with a second inner support arm 201, and the bottom end of the second inner support arm 201 is fixedly connected to the second inner support block 202, the right side of the first inner support block 102 and the left side of the second inner support block 202 are both provided with an anti-slip layer 6, and the surface of the first inner support block 102 and the second inner support block 202 in contact with the anti-slip layer 6 is an arc structure, and the first inner support arm 101 The outer sides of the first and second inner support arms 201 are both covered with a silicone layer, and the area covered by the silicone layer is an acid-proof area. A notch is provided in the middle of the second inner support arm 201, and a guide groove 203 is provided on the bottom surface of the power arm 2. The top of the elastic arm 502 fits in with the inner top surface of the guide groove 203. When in use, hold the handle 1 and the power arm 2 between the palms of your hands, and then extend the first inner support block 102 and the second inner support block 202 into the circular groove in the middle of the inner cover of the chemical reagent, then press down the power arm 2, and the power arm 2 rotates with the connecting shaft 3 as the fulcrum, thereby driving the second inner support block 202 is away from the first inner support block 102. At this time, the two inner support blocks are respectively in contact with the inner wall of the groove of the inner cover of the chemical reagent. The anti-slip layer 6 can prevent the inner support block and the inner cover from slipping. Then, the inner cover is pulled out from the mouth of the reagent bottle with upward force. The handle 1 and the power arm 2 are longer than the two inner support arms, that is, the power arm 2 is larger than the resistance arm, which is more labor-saving to use. Only a light grip is needed to make the inner support block close to the groove of the inner cover.

Two torsion springs 503 are sleeved on the outer sides of the two ends of the rotating shaft 501, and the two torsion springs 503 do not contact the rotating shaft 501. The two ends of the two torsion springs 503 are respectively connected to the inner wall of the mounting groove 5 and the outer side of the elastic arm 502. The elastic arm 502 and the handle 1 are connected by the two torsion springs 503 to form an elastic reset structure; in normal state The top of the lower elastic arm 502 fits in with the guide groove 203 on the bottom surface of the power arm 2, and the elastic force of the torsion spring 503 is used to make the elastic arm 502 push the power arm 2 and the handle 1 apart. At this time, the first inner support block 102 and the second inner support block 201 fit in with each other, making it convenient to place the two inner support blocks into the groove on the top surface of the inner cover. In the process of pressing down the power arm 2, the top of the elastic arm 502 will slide along the guide groove 203, making the elastic arm 502 more stable when sliding, avoiding deviation and damage.

At this time, the second inner support arm 201 will drive the second inner support block 202 away from the first inner support block 102, so that the anti-slip layer 6 on the first inner support block 102 and the second inner support block 202 fits on the inner wall of the inner cover, and the handle 1 and the power arm 2 are compared with the two inner support arms. It is longer, that is, the power arm 2 is larger than the resistance arm, and it is more labor-saving to use. You only need to gently grip the inner support block to fit tightly into the groove of the inner cover, and then pull out the inner cover upwards.
