Knob to be pulled out is placed in cavity by first shell and second shell, be then closed first shell and second shell and by it upwards
Knob is extracted in drawing.
The utility model is also characterized by
The bottom surface of the first shell and second shell is respectively arranged with the first half bore and the second half bore, first half bore
The circular hole to be formed for fixed knob valve rod to be pulled out is matched with the second half bore.
The top surface of the first shell and second shell, which extends outward to form semicircular first and pulls out ear and second, pulls out ear,
After the first shell and second shell are closed, first, which pulls out ear and second, pulls out ear and is closed to be formed and circular pull out ear.
The connection component includes fulcrum, the first cylinder and the second cylinder, and first cylinder is set on fulcrum simultaneously
It is connected with first shell, second cylinder is set on fulcrum and is connected with second shell.
The fulcrum is threaded.
Further comprise thread plug, the thread plug be arranged on threaded lower end for the first cylinder and the second cylinder into
Row /V.
The diameter of the thread plug is more than the diameter of the first cylinder and the second cylinder.
The first shell pulls out ear integrated molding with first.
The second shell pulls out ear integrated molding with second.
Compared with prior art, when the utility model is used, first shell and second shell are opened along connection component, will treated
It pulls out knob to be placed in cavity, be then closed first shell and second shell and pulled up, extract knob, the knob of extraction
It can stay in cavity, knob is avoided due to inadvertently falling off the situation for breaking damage to be caused to occur.
Description of the drawings
Fig. 1 is that the utility model embodiment provides a kind of structure diagram pulled out when knob tool is in opening；
Fig. 2 is that the utility model embodiment provides a kind of structure diagram pulled out when knob tool is in closure；
Fig. 3 is that the utility model embodiment provides a kind of sectional view for pulling out knob tool；
Fig. 4 is that the utility model embodiment provides a kind of usage state diagram for pulling out knob tool.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further elaborated the utility model.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
The utility model embodiment provides one kind and pulls out knob tool, as shown in Figs. 1-3, including first shell 1, second shell
Body 2 and connection component 3, first shell 1 and second shell 2 are oppositely arranged and form cavity 4, first shell 1 and second shell 2
It is connected with connection component 3；In this way, opening first shell 1 and second shell 2 along connection component 3, knob to be pulled out is placed in cavity
In 4, then it is closed first shell 1 and second shell 2 and is pulled up, extract knob.
The bottom surface of first shell 1 and second shell 2 is respectively arranged with the first half bore 11 and the second half bore 21, the first half bore 11
It is formed for the circular hole 5 of fixed knob valve rod to be pulled out with the matching of the second half bore 12, in this way, knob valve rod is placed in circular hole 5, kept away
The damage to knob valve rod is exempted from.
The top surface of first shell 1 and second shell 2, which extends outward to form semicircular first and pulls out ear 12 and second, pulls out ear
22, after first shell 1 and second shell 2 are closed, first pull out ear 12 and second pull out the closure of ear 22 formed it is circular pull out ear 6, first
Housing 1 pulls out ear 12 with first and is integrally formed, and second shell 2 is pulled out ear 22 with second and is integrally formed, in this way, conveniently being made by pulling out ear 6
User operates stress, and extraction dynamics is smaller than singly pulling out knob.
Connection component 3 includes fulcrum 31, the first cylinder 32 and the second cylinder 33, and the first cylinder 32 is set on fulcrum 31
And be connected with first shell 1, the second cylinder 33 is set on fulcrum 31 and is connected with second shell 2, and fulcrum 31 is threaded, this
Sample, the first cylinder 32 and the second cylinder 33 drive first shell 1 and second shell 2 to move in the opposite direction, make first shell 1
It opens or is closed with second shell 2.
Further comprise thread plug 34, thread plug 34 is arranged on threaded lower end for the first cylinder 32 and the second cylinder
33 carry out /V, and the diameter of thread plug 34 is more than the diameter of the first cylinder 32 and the second cylinder 33, was being used in this way, avoiding
The first cylinder 32 and the second cylinder 33 slide from fulcrum 31 in journey.
Application method：As shown in figure 4, the first cylinder 32 first and the second cylinder 33 drive first shell 1 and second respectively
Housing 2 moves in the opposite direction, opens first shell 1 and second shell 2, and knob to be pulled out is placed in first shell 1 and
