Therefore, when the pulmonary arterial hypertension is treated, the device can meet the requirements of different individuals, surgery is carried out at a more accurate sympathetic nerve position through the combination of stimulation and ablation, and the treatment effect is improved.

The utility model provides an air injection component for a mask storage cabinet, which comprises a nozzle and a clamp, the clamp comprises a clamping arm, a first arm and a second arm, the clamping arm is connected with the first arm, and the clamping arm clamps and fixes the nozzle; one end of the second arm is elastically connected with the first arm, so that elastic force towards the first arm is applied to the second arm, and the first arm and the second arm clamp a diaphragm plate of the mask storage cabinet. According to the mask storage box, the risk that the nozzle falls off can be eliminated, and it is guaranteed that gas can smoothly enter the mask storage box through the nozzle all the time, so that the storage environment of the mask meets the requirement of process testing.

The utility model provides a kind of oil pipe sealing ring with spiral drainage groove, it is related to oil pipe sealing ring technical field, including primary oil pipe, secondary oil pipe and primary flange ring, connecting mechanism is equipped between primary flange ring and secondary flange ring, sealing ring is equipped between primary oil pipe and secondary oil pipe, the inside of sealing ring is equipped with spiral groove, the inside of secondary flange ring is equipped with tensioning mechanism;The utility model is compressed after primary flange ring and secondary flange ring clamp primary oil pipe and secondary oil pipe, drive spring to be in compression state, spring generates the elastic force to drive sealing ring and secondary oil pipe to be close to primary oil pipe, so that primary oil pipe, secondary oil pipe and sealing ring are closely attached between, so that sealing effect is better, and primary flange ring and secondary flange ring are wrapped sealing ring, to solve the problem that outer ring of sealing ring in the prior art is easily damaged by scratching, and the sealing ring is broken in serious cases.

The disclosure provides a battery and a manufacturing method therefor, and a power consuming device. The battery includes: a sampling apparatus; and at least two battery cells arranged in a first direction, where ends of the battery cells are provided with terminal posts, and an extending direction of the terminal posts protruding from the ends of the battery cells is perpendicular to the first direction. The sampling apparatus includes a sampling element having a built-in sampling signal line, at least two mounting portions are formed on the sampling element, and the mounting portions match side shapes of the terminal posts, so that the mounting portions are closely attached to the terminal posts of the corresponding battery cells; and the sampling apparatus further includes a connection portion connected to the sampling signal line, and the connection portion is configured to electrically connect the mounting portions and the terminal posts. After the sampling apparatus and the battery cells are assembled, the sampling apparatus may not protrude from the surface of the battery cells by fully utilizing a redundant space between the battery cells, to reduce the occupation of a space within the battery by the sampling apparatus. This is conductive to further increasing the energy density of the battery.

The invention discloses a bending device for reducing stainless steel bending die marks and a bending method thereof, and relates to the technical field of machining, the bending device comprises a positioning seat, lower fixing dies are symmetrically installed on the upper portion of the positioning seat left and right, and a plurality of lifting reset assemblies are installed on the side walls of the lower fixing dies; a lower moving die is installed in the middle of the lifting reset assembly, a downward pressing and bending assembly is arranged above the lower moving die, a bending protection film is arranged on the upper surface of the lower fixed die, and an adsorption assembly used for adsorbing and positioning the bending protection film is installed in the lower fixed die. The other side wall of the lower fixed die is provided with a roller body assembly used for guiding and bending a protective film. The bending protective film solves the problems that an existing bending protective film is difficult to protect a non-V-shaped workpiece and a die, the protective film is difficult to be effectively attached between the non-V-shaped workpiece and the die, and even normal operation of the bending process is affected.

The utility model belongs to the field of machinery, and relates to an elastic plate hole clamping and adjusting device which comprises a lug hole penetrating elastic plate, a swing arm connecting piece, a supporting wheel swing arm, a lug hole penetrating piece and a lug plate blocking shifting pin, the lug hole penetrating elastic plate comprises a lug plate penetrating hole, a shifting pin penetrating and blocking sleeve is arranged at one end of the swing arm connecting piece, and a supporting wheel swing arm connecting structure is arranged at the other end of the swing arm connecting piece. The ear perforating piece is provided with a clamping and sticking elastic plate piece and a perforating ear, the perforating ear penetrates through the ear penetrating plate hole, the penetrating and blocking movement pin shaft sleeve penetrates through the ear penetrating plate hole, and the ear blocking plate movement pin penetrates through the perforating ear and the penetrating and blocking movement pin shaft sleeve, so that the clamping and sticking elastic plate piece is tightly attached to the ear penetrating hole elastic plate; the clamping and pasting elastic plate piece and the lug blocking plate moving pin prevent the perforated lug from falling off from a lug penetrating plate hole from the two sides of the lug penetrating hole elastic plate, the supporting wheel rocker arm is pushed by external force to be connected with the swing arm piece, the swing arm piece pushes the lug blocking plate moving pin, the lug blocking plate moving pin transmits the external force to the lug perforating piece, and the clamping and pasting elastic plate piece pushes the lug penetrating hole elastic plate to elastically deform and buffer. And the ear-hole-penetrating elastic plate is quickly straightened to reset by the buffer bounce of the ear-hole-penetrating elastic plate.
